About CZNull
We maintain a small, opinionated collection of graphics micro-benchmarks that you can trigger from a URL—ideal for quick hardware smoke tests and classroom demos.
About CZNull
Traditional suites often assume a desktop installer. CZNull instead leans on WebGL so an Android user, a Chromebook student, and an engineer on Linux can share vocabulary about the same shader cost.
Community interest in volumetric and ray-marched demos inspired several of our longest-running pages. We document what each pass does in plain language because a GPU measurement is only as honest as its disclosed workload.
Source and collaboration discussions sometimes happen on public GitHub-style workflows; the site itself is the canonical place to run the latest packaged tests.
Principles
Clarity over marketing
We describe limits—what is simulated in a fragment shader versus true API ray tracing, for example—so you know which subsystem you are exercising.
Low friction
No mandatory signup to see a live chart; if WebGL is available, you can collect data.
Cross-platform parity
Where APIs allow, identical GLSL paths run on mobile and desktop browsers to keep comparisons honest.
